摘　　要：以边坡模型试验为例,证明光纤光栅传感技术在克服电磁干扰、提高耐久性等方面的优越性.边坡模型在加载至36 kN时,坡面开始较明确的裂缝,在完成39 kN加载后,坡面出现更多裂缝,并且裂缝逐渐发展贯通,证明边坡已经发生破坏,坡面裂缝贯通,部分土体沿坡面滑落.最后,利用试验数据剖析了加筋边坡的工作机理,阐述了土工格栅对提高边坡稳定性的意义.Take slope model test as an example,the superiority of fiber grating technology for overcoming electromagnetic interfernce and improving durability,etc.was verified.Slope model is loaded to 36 kN,the slope of the cracks began to appear more obious.After the completion of 39 kN load,slope appeared more cracks,and cracks gradually developed through,which shows that the damage of the slope,the slope through cracks,part of the soil sliding along the slope have appeared.Finally,the workflow mechanism of slope was analyzed by the data of model test,and the significance of geo-grid to improve slope stability was described.
